Mo-fi Ultradeck owners - popping noise from speaker upon power off


Guys, I got a mo-if ultradeck with mastertracker cartridge and I have a problem that I cannot figure out. When I turn the power switch off, I get a loud pop through my speakers. If turn the volume down or switch to another channel, then obviously I do not hear it.

I got the player replaced with another new unit and the same thing. I have tried everything - that I can physically do, replace power cord, hook up power cord to a different outlet, using different phono preamp, etc.

Does anyone else experience this? My other Project Classic SB TT does not have this at all in the same system.

I have searched the whole internet and found one post on Stevehoffman forum about experiencing the same and that person did all sorts of experimentation to no avail.

A $2500 player should NOT have issues like this. Period.

As others have noted, I had this issue with my VPI Classic 2.  VPI sent me a replacement capacitor for the motor (for free).  It was very easy to swap out and fixed the problem.
Either a bad cap or sloppy engineering. My cheapo Sony 4k player does this, occasionally,  when resuming from pause. Hope it doesn't blow out my tweeters.
